Adult personality disorders are well recognized and described in the literature. The discussion about the possibility of the presence of personality disorders in adolescents started about 20 years ago. Some authors claim the before the age of 18 it is only possible to identify precursors of future personality disorders and such a standpoint is reflected in diagnostic criteria. This is based on the assumption that personality in adolescence is still not well established. Consequently, the criterion on the persistence of symptoms for the period of time cannot be met (the persistence of symptoms of personality disorders for the period of at least two years). Other approach postulates that problems presented in adolescence should not be exclusively limited to Axis I according to DSM. The proponents of this approach claim that current diagnostic tools are not adjusted to adolescents, thus it is very difficult to measure stability and persistence of symptoms in this age group. This paper presents literature review on personality disorders in adolescence.
